View point, School of thought, legal jurispudance and method of reason on how to act in a particular situation.
There are four schools of thought namely Hanafi which is largely followed, Maliki, Shafi and Hanmbali.
Unless one has full knowledge of jurispudance ( deep Islamic understanding of law) it may be better to follow a school of thought, but not blindly. One can also be open to following all four depending on the situation he or she is in. Again blind following is not encouraged, it is better to always research as all four are based on humans, and humans are faulty ( can make mistakes)
